Given numbers are 961, 640, 261
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(961, 640) = 615040
GCD(961, 640) = ( 961 x 640 ) / 615040
= 961 / 640
= 961
Step2:
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
= 1 / 261
= 1
So, Greatest Common Divisor of 961, 640, 261 is 1
